New Product Category Rule for Clay Brick Published by ASTM

Words: Dan KamysWith support from the brick industry, ASTM has published a new Product Category Rule (PCR) for clay brick products. This significant milestone allows for development of North American Environmental Product Declarations (EPDs) for clay brick products, including brick, pavers and structural clay tile. The formal name is the Clay Brick, Clay Brick Pavers, and Structural Clay Tile PCR.
The product group includes manufactured masonry units made by forming and ring prepared mixtures of clay, shale and other materials. These are generically known as clay brick, clay brick pavers, and structural clay tile. Specific products are listed in Section 3.0 definitions and are given in Table 1. The full PCR can be found as a PDF on the ASTM website.
